Seven different schemes were launched in different months - March, April, May, June, August, September and November, one after the other.
The schemes were - Gold, House, Solar, Car, Mutual fund, Grocery and Flat.
Flat scheme was launched in June.
Gold scheme was launched immediate before Car scheme.
Two schemes were launched between Gold scheme and House scheme, which was not launched before Flat scheme.
| Months | Schemes |
| March | |
| April | Gold |
| May | Car |
| June | Flat |
| August | House |
| September | |
| November | |
Atleast three schemes were launched between Solar and Grocery.
| | Case 1 | Case 2 |
| Months | Schemes | Schemes |
| March | Solar/Grocery | Solar/Grocery |
| April | Gold | Gold |
| May | Car | Car |
| June | Flat | Flat |
| August | House | House |
| September | Solar/Grocery | |
| November | | Solar/Grocery |
Grocery scheme was launched after Mutual Fund. Thus, case 1 is invalid.
So, the final arrangement is:
| Months | Schemes |
| March | Solar |
| April | Gold |
| May | Car |
| June | Flat |
| August | House |
| September | Mutual fund |
| November | Grocery |
Except option (c), in all other options, the given schemes were launched immediate after the given months.
But the scheme of Solar was launched immediate before April.
